The housing 15 is insert-molded in a state where it is disposed in the position. And the front-end | tip part which has the hole 47 for fastening of each connection tab part 46 of these connection terminals 21 protrudes from the mounting part 12 of the housing 15. FIG.

接続端子２１をインサート成形する場合、まず、接続端子２１のケーブル圧着部４４にケーブル１１を圧着して接続し、ケーブル１１にシールゴム４１を成形によって設ける。その状態で、これらの接続端子２１をハウジング１５の成形用金型にセットし、金型へ樹脂を射出成形する。これにより、接続端子２１がインサート成形されたハウジング１５が得られる。   When insert molding the connection terminal 21, first, the cable 11 is crimped and connected to the cable crimping portion 44 of the connection terminal 21, and the seal rubber 41 is provided on the cable 11 by molding. In this state, these connection terminals 21 are set in a molding die of the housing 15 and resin is injection molded into the die. Thereby, the housing 15 in which the connection terminal 21 is insert-molded is obtained.

このように、接続端子２１をインサート成形によってハウジング１５に一体化すると、各接続端子２１の間に樹脂が入り込むこととなる。これにより、接続端子２１は、ハウジング１５に確実に保持され、また、各接続端子２１同士の間では、沿面距離等を考慮することなく、絶縁が確保される。   As described above, when the connection terminals 21 are integrated with the housing 15 by insert molding, the resin enters between the connection terminals 21. Thereby, the connection terminal 21 is reliably hold | maintained at the housing 15, and insulation is ensured between each connection terminal 21, without considering creepage distance etc.

また、コネクタ１０には、ハウジング１５の装着部１２に、インターロック端子４８が接続されるインターロック部４９が成形されている。   The connector 10 is formed with an interlock portion 49 to which the interlock terminal 48 is connected to the mounting portion 12 of the housing 15.

上記構造のコネクタ１０を機器に接続するには、コネクタ１０の装着部１２を機器のケースに形成された取付孔へ嵌め込む。このように、機器のパネルの取付孔へ装着部１２を嵌め込むと、装着部１２に取り付けられているシール部材１７が取付孔の内周面に密着し、機器とコネクタ１０とが防水される。   In order to connect the connector 10 having the above structure to a device, the mounting portion 12 of the connector 10 is fitted into a mounting hole formed in the case of the device. As described above, when the mounting portion 12 is fitted into the mounting hole of the device panel, the seal member 17 attached to the mounting portion 12 is in close contact with the inner peripheral surface of the mounting hole, and the device and the connector 10 are waterproofed. .

そして、装着部１２から突出されている３つの接続タブ部４６の締結用孔部４７に締結ボルト（図示略）を挿入し、この締結ボルトを機器の内部に設けられた端子台の接続端子（図示略）にねじ込む。このようにすると、接続タブ部４６が端子台の接続端子に接続され、各ケーブル１１と端子台の接続端子に接続された機器内の配線とが導通される。   Then, fastening bolts (not shown) are inserted into the fastening hole portions 47 of the three connection tab portions 46 protruding from the mounting portion 12, and the fastening bolts are connected to the connection terminals ( Screw in (not shown). If it does in this way, the connection tab part 46 will be connected to the connection terminal of a terminal block, and each cable 11 and the wiring in the apparatus connected to the connection terminal of a terminal block will be conducted.

さらに、シールドシェル２４の取付片２５の孔部２５ａへネジを挿入し、機器側のネジ孔へねじ込み、シールドシェル２４を機器のケースに導通接続させる。すると、コネクタ１０の機器の外側に配置されるケーブル導入部１３を覆うシールドシェル２３，２４が機器に導通接続され、良好なシールド効果が得られる。   Further, a screw is inserted into the hole 25a of the mounting piece 25 of the shield shell 24 and screwed into the screw hole on the device side, and the shield shell 24 is conductively connected to the case of the device. Then, the shield shells 23 and 24 covering the cable introduction portion 13 arranged outside the device of the connector 10 are conductively connected to the device, and a good shielding effect is obtained.

このように、上記実施形態に係るコネクタによれば、複数本のケーブル１１が接続される複数のケーブル圧着部４４と一つの接続タブ部４６とを有する合流型の接続端子からなる−極接続端子２１Ｚを備えているので、接続端子２１を保持するハウジング１５の小型化を図ることができる。特に、接続相手である機器側の端子台に接続される接続タブ部４６の数が少なくされるので、取付孔へ嵌め込まれる装着部１２を小さくすることができる。これにより、シール部材１７による取付孔とのシール範囲を少なくすることができ、シール性を高めることができる。   Thus, according to the connector which concerns on the said embodiment, the negative electrode connection terminal which consists of a confluence-type connection terminal which has the some cable crimping | compression-bonding part 44 and the one connection tab part 46 to which the several cable 11 is connected. Since 21Z is provided, the housing 15 that holds the connection terminal 21 can be downsized. In particular, since the number of connection tab portions 46 connected to the terminal block on the device side that is the connection partner is reduced, the mounting portion 12 fitted into the attachment hole can be made smaller. Thereby, the sealing range with the attachment hole by the sealing member 17 can be decreased, and a sealing performance can be improved.

また、合流型の接続端子である−極接続端子２１Ｚと他の接続端子である＋極接続端子２１Ｙとの交差箇所をハウジング１５の厚さ方向の異なる位置に配置したので、−極接続端子２１Ｚと＋極接続端子２１Ｙとの絶縁を確保しつつ、接続タブ部４６及びケーブル圧着部４４の配列方向であるハウジング１５の幅方向の大きさを抑えて小型化を図ることができる。   In addition, since the intersections between the −pole connection terminal 21Z which is a junction type connection terminal and the + pole connection terminal 21Y which is another connection terminal are arranged at different positions in the thickness direction of the housing 15, the −pole connection terminal 21Z. The size of the housing 15 in the width direction, which is the arrangement direction of the connection tab portion 46 and the cable crimping portion 44, can be reduced while ensuring insulation between the positive electrode connection terminal 21Y and the positive electrode connection terminal 21Y.

しかも、インサート成形によってハウジング１５に接続端子２１を一体的に設けたので、ハウジング１５に接続端子２１を確実に保持させることができ、接続端子２１同士の良好な絶縁を確保することができる。   In addition, since the connection terminals 21 are integrally provided in the housing 15 by insert molding, the connection terminals 21 can be reliably held in the housing 15 and good insulation between the connection terminals 21 can be ensured.

なお、上記実施形態では、装着部１２とケーブル導入部１３とが側面視でＬ字状に形成されたコネクタを例示したが、装着部１２とケーブル導入部１３とは、直線状に形成されていても良い。この場合、図８に示すように、各接続端子２１は、圧着接続部４３に対して接続タブ部４６がケーブル１１の長手方向に沿って延在する形状となる。また、この場合、＋極接続端子２１Ｙは、連結板部４５と接続タブ部４６との間にも段部４３ｂを形成し、−極接続端子２１Ｚの連結板部４５に対して＋極接続端子２１Ｙの連結板部４５が接触することなく、間隔をあけた状態に配置されるようにする。   In the above-described embodiment, the connector in which the mounting portion 12 and the cable introduction portion 13 are formed in an L shape in a side view is illustrated, but the mounting portion 12 and the cable introduction portion 13 are formed in a straight line shape. May be. In this case, as shown in FIG. 8, each connection terminal 21 has a shape in which the connection tab portion 46 extends along the longitudinal direction of the cable 11 with respect to the crimp connection portion 43. In this case, the + pole connection terminal 21Y also forms a step 43b between the connection plate portion 45 and the connection tab portion 46, and the + pole connection terminal with respect to the connection plate portion 45 of the −pole connection terminal 21Z. The connecting plate portion 45 of 21Y is arranged in a spaced state without contact.

ここで、本発明の更なる優位性を説明するため、図９及び図１０に参考例を示す。   Here, in order to explain the further superiority of the present invention, reference examples are shown in FIGS.

図９は、参考例に係るコネクタの斜視図、図１０は参考例に係る接続端子の斜視図である。   FIG. 9 is a perspective view of a connector according to a reference example, and FIG. 10 is a perspective view of a connection terminal according to the reference example.

図９及び図１０に示すように、この参考例に係るコネクタ５１は、４つの接続端子５２を有しており、これらの接続端子５２が、ケーブル導入部５３から導入される４本のケーブル５４にそれぞれ接続されて並列に配置されている。そして、このコネクタ５１では、装着部５５から接続端子５２の接続タブ部５６が間隔をあけて並列に突出されている。   As shown in FIGS. 9 and 10, the connector 51 according to this reference example has four connection terminals 52, and these connection terminals 52 are introduced by four cables 54 introduced from a cable introduction portion 53. Are connected in parallel and arranged in parallel. And in this connector 51, the connection tab part 56 of the connection terminal 52 protrudes in parallel from the mounting part 55 at intervals.

このようなコネクタ５１では、それぞれのケーブル５４に接続された接続端子５２の接続タブ部５６が間隔をあけて並列に配置されているので、大型化を招いてしまう。特に、機器の取付孔へ嵌め込まれる装着部５５が大型であるため、取付孔とのシール範囲が広くなり、シール性の低下を招くおそれがある。   In such a connector 51, since the connection tab portions 56 of the connection terminals 52 connected to the respective cables 54 are arranged in parallel at intervals, the size of the connector 51 is increased. In particular, since the mounting portion 55 to be fitted into the mounting hole of the device is large, a sealing range with the mounting hole is widened, and there is a possibility that the sealing performance is deteriorated.
